SARQUIS, Ana Lúcia F.; MIYAKI, Mitsuru and CAT, Mônica N. L.. The use of CRIB score for predicting neonatal mortality risk. J. Pediatr. (Rio J.) [online]. 2002, vol.78, n.3, pp. 225-229. ISSN 1678-4782. http://dx.doi.org/10.1590/S0021-75572002000300011.
Objective: to examine the clinical risk index for babies (CRIB) predictive value for hospital death; to identify the score variable with the best predictive value and to compare CRIB score capability to predict hospital mortality to birth weight, gestational age and base excess. Methods: CRIB score was obtained through a prospective way from 100 newborns with birthweight of 1,500 g or less or gestational age less than 31 weeks, who were admitted consecutively to the Neonatal Unit of Hospital das Clínicas, Universidade Federal do Paraná. Results: Fifty-five newborns were females and 45 were males, the average birthweight was 1,078 ± 0.277 g and gestational age was 29.2 ± 2.8 weeks. Twenty-one patients died. The mortality rate in the CRIB groups 1, 2, 3 and 4 was, respectively 6.6%; 46.2%; 87.5% and 100.0%. The score accuracy for mortality was confirmed (area under the ROC curve = 0.877) and the best score variable to predict hospital death was maximum base excess (area under the ROC curve = 0.795). Compared with birthweight and gestational age, CRIB was significantly better to predict mortality. Conclusions: Besides being useful to predict hospital death, CRIB was a simple score to be applied. Based on these results, we recommend its inclusion in the routine of neonatal units.
